Can You Be Defected For Having No Bov?

[Bennis]

Hey guys,

The R33 I just bought has no BOV and as you would expect has your typical no-bov flutter from the air bouncing back and forth. The flutter only occurs when you put a fair bit of load on the engine and it begins to build boost (2800-3000rpm)... Its a GT3582R btw and atm has a pod but am reverting to standard airbox so you cannot always hear it but its still there and would dare say be quieter with the stock airbox.

The big question is, if a cop, 'somehow' were to hear the flutter, could they pull you up and try and get you for an atmo bov (because they probably cannot tell the difference in sounds). If you tried to argue that you do not have one they would probably not believe you etc etc.

Point is, can I technically be defected for this? Has anyone had something like that happen or a similar circumstance. I dont want to have to buy a plumb back BoV just to make it quiet if I dont have too.

Cheers

Yes, but surely you'd be more worried about the f**koff big turbo.

[AngryRB]

why don't you plumb a stock blow off valve in but block it with a plate?..

[Joshbigt62r]

Exactly what I done angryrbgtx. Just don't dose it bro next or near a police man/lady and you'll be right.

[Bennis]

Its not a loud exaggerated 'dose' like you normally hear its actually really quiet and short with no high pitch lol and doesnt happen if youre just cruising which is good because Im not really into the whole fully hektikkkk dose thing haha.

And yes I am more worried about the huge turbo and will be going to my own measures to make that less sus (probably to no avail).

Could do that angry but its still the whole buying and paying someone to weld it in. It hasnt go any stock piping.

[HEKT1K]

Then don't bother. Sounds like your car is a defect waiting to happen, just fix it all if/when you get done

Whack the stock BOV on, pipe it up, then blank it off. Gonna be some effort to fit the stock airbox in with that turbo. I'm gonna assume its got a big intake pipe with a pod on the end. I'd say just make a box out of metal and paint it black. The stock airbox is probably the last concern on any modified skyline drivers mind.

In my old S14, ran no BOV, came out of a round-a-bout one night and shifted gears, cop heard the flutter and pulled me over..

Basically said he heard my BOV, but after explaining it was removed and wasnt running a BOV at all he just left it at that.

Each copper will be different, if they want to defect you, they can and will. Treat them with respect and they may just leave you be.

My 2cents..

No you can't be defected for no BOV. If the cop is a dick he will issue you with a DECC inspection notice and then the inspector will pick out all your defects.

[Bennis]

Thanks for the replies, my question is pretty much answered

[GTSBoy]

No you can't be defected for no BOV. If the cop is a dick he will issue you with a DECC inspection notice and then the inspector will pick out all your defects.

You can. Technically, being part of the inlet tract, it is part of the emissions system and is therefore verboten to alter.

[NYTSKY]

Technically you are correct however a cop won't defect you for a BOV if he cannot see it.

Both times I have had my car DECC inspected I was told by the inspector "Remove your BOV because the people at the EPA don't like seeing them"

That comment alone tells me the pen pushers there are inconsistent in their rulings.

[paulr33]

in summary, you can be defected for any modification (removal, addition, change) to the intake / turbocharger system

regardless of what or why

its simply a matter of if the relevant authority notices the modification (removal, addition or change)

[Kane_R32]

Technically you are correct however a cop won't defect you for a BOV if he cannot see it.

I have been defected for an aftermarket ECU, copper couldn't see it.

Basically the police will defect you if the believe its modifies/not original. Then you have to prove it to whoever is clearing the defect.

[Tommmay]

What happens if you have a big engine cover so they cant see anything

Make up some screws that only you have the tool for

lol

[jiffo]

It's been a while since I've seen one but I'm sure the autos came from factory without a BOV?

[GTSBoy]

Nuh. No difference.

[Bitsushiti]

I'd say nope, not defectable. When my 33 first went over the pits 5 years ago when I didn't know any different, first thing they spotted was my atmo BOV. Got told to block it off, so I replaced it with a blanking plug and they gave the all clear.

[GTSBoy]

Just because you didn't get done doesn't mean it's not defectable. This will vary from cop to cop, inspection station to inspection station, inspector to inspector and state to state.

Cops can't defect you for no

Blow off valve suppose they could but that would be a joke why would they waste there time.
